I also think that the liberal/conservative thing is too broad,
take me for example:
I am pro gun, think murderers and rapists should fry, support funding for a powerful military, and don't believe in giving lazy "refugees" from Cuba my money as welfare;
however I am also pro-choice, dislike religion in general, don't really care about government buggering into people's private lives with "morality" (gay marriage is an example)and think that we should spend more Federal money on education and science (even if it means raising taxes, especially on the upper class)

as you see I have opinions that are both stereotypical "conservative" and stereotypical "liberal" opinions.
